🔍 Perplexity MCP Server

Perplexity-backed code analysis and debugging — straight from your Claude conversation.

A Model Context Protocol (MCP) server that lets Claude (or any MCP client) ask Perplexity AI for code analysis, error explanations, and debugging help.

Features

• 🐛 Intelligent Error Analysis — Root-cause breakdown of coding errors
• 🔬 Pattern Detection — Recognizes common error patterns and provides targeted solutions
• ✅ Comprehensive Solutions — Step-by-step fixes with multiple implementation alternatives
• 📚 Best Practices — Coding standards and error-prevention tips
• 🐍 Python Support — Specialized handling of Python type errors and common issues

Example usage

Ask Claude:

"Fix this TypeError in my Python code" "What's causing this error message?" "How do I fix this code?"

Include your code snippet:

def calculate_total(items):
    total = 0
    for item in items:
        total = total + item['price']  # TypeError: string + int

data = [
    {'name': 'Book', 'price': '10'},
    {'name': 'Pen', 'price': '2'}
]

result = calculate_total(data)

The server returns:

1. Root-cause analysis of the error
2. Step-by-step solution with code examples
3. Best practices to prevent the same issue
4. Alternative implementations
